1. Make sure you have the latest version of tesseract.
Then try this script and provide exact/full error message:
import tempfile
import cv2
import pytesseract
from PIL import Image
from pytesseract import Output
pytesseract.pytesseract.tesseract_cmd = 'C:\\Program
Files\\Tesseract-OCR\\tesseract.exe'
*i*mg = cv2.imread('images/invoice-sample.jpg')
# check temp file
temp_file = tempfile.NamedTemporaryFile(prefix='tess_')
print(temp_file.name)
image = Image.fromarray(img)
image.save(temp_file.name + '.png', format='png', **image.info)
temp_file.close()
if img.any():
print("Image shape:", img.shape)
data_dict = pytesseract.image_to_data(img, output_type=Output.DICT)
n_boxes = len(data_dict['level'])
for i in range(n_boxes):
(x, y, w, h) = (data_dict['left'][i], data_dict['top'][i], data_dict['width'
][i], data_dict['height'][i])
cv2.rectangle(img, (x, y), (x + w, y + h), (255, 125, 125), 2)
cv2.imshow('img', img)
cv2.waitKey(0)
else:
print("Can not open input file")
